[0026] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] Existing intravenous hemostasis usually uses a bandage to press and stop bleeding. The bandage is not only difficult to apply pressure, but also requires the patient to press for a long time to completely stop the bleeding, and the hemostasis effect is poor.

[0028] Based on the above prior art, the utility model provides an improved hemostatic dressing, as shown below:

[0029] like Figure 1 and Figure 2As shown, a hemostatic dressing includes a hemostatic layer 1, an anti-infection layer 2 and gauze 5, the anti-infection layer 2 is arranged on the hemostatic layer 1, the gauze 5 is arranged at the center of the anti-infection layer 2, and the gauze 5 is arranged in a spiral shape and is rolled into a ring structure along the center of the anti-infection layer 2.

[0030] In specific implementation, Figure 1 and Figure 2 As shown, the hemostatic layer 1 is used to stop bleeding of the patient's wound, and the anti-infection layer 2 is used to prevent infection of the patient's wound. Then, the device is pressed to the patient's wound. Since the spiral gauze 5 is provided, the gauze 5 is wound into a ring structure along the center of the anti-infection layer 2, so that the pressure is concentrated by pressing the gauze 5, and the patient's wound can be quickly stopped bleeding, reducing the patient's hand pressing time and achieving a better hemostatic effect. It can be understood that when the gauze 5 is set at the center of the anti-infection layer 2, at this time, the pressing pressure of the gauze 5 is more likely to act on the wound.

[0031] It should be noted that the spiral type of gauze 5 means that the gauze 5 is curled into a structure similar to a hemp rope, so that the gauze 5 is in a taut state, and then rolled into a ring structure along the center of the anti-infection layer 2, which further puts the gauze 5 in a taut state, causing the pressing pressure to be greater and more concentrated.

[0032] See also Figure 1 As shown, in a preferred embodiment of the present utility model, a water-absorbing layer 3 is arranged on the anti-infection layer 2, and the gauze 5 is arranged on the water-absorbing layer 3.

[0033] In specific implementation, Figure 1 As shown, the water-absorbing layer 3 is arranged on the anti-infection layer 2, and the water-absorbing layer 3 is used to absorb blood, prevent the blood from penetrating into the gauze 5, and play a certain waterproof role. It can be understood that the gauze 5 in this solution is first spiral-shaped and then wound into a ring structure. Since the gauze 5 is easily softened when it meets water, and there is a lot of water in the blood, the structural stability of the gauze 5 is improved by the arrangement of the water-absorbing layer 3.

[0034] Furthermore, the water-absorbing layer 3 is a medical water-absorbing transparent layer.

[0035] In specific implementation, the medical water-absorbing transparent layer refers to medical water-absorbing materials and transparent materials. The medical materials need to meet special requirements, be non-toxic, non-irritating, and easy to sterilize, such as hydrophilic non-woven fabrics, hydrogel materials, polyurethane (PU) films, etc. By using medical water-absorbing transparent materials to make the water-absorbing layer 3, the water-absorbing layer 3 can not only absorb blood in a waterproof manner, but also observe the hemostasis situation, so that the patient can release the pressing arm in time.

[0036] In a preferred embodiment of the present invention, the water absorbing layer 3 and the anti-infection layer 2 are integrally formed.

[0037] In a specific implementation, the water absorbing layer 3 and the anti-infection layer 2 are integrally formed to increase the structural strength of the device and extend the service life of the device.

[0038] See also Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the water absorbing layer 3 is adhesively connected to the gauze 5.

[0039] In a specific implementation, the bottom of the water-absorbing layer 3 is fixedly connected to the anti-infection layer 2, and the top of the water-absorbing layer 3 is connected to the gauze 5 by adhesive bonding. Adhesive bonding refers to the use of glue, double-sided tape, solid glue and other glue-like materials to achieve adhesion. More specifically, the water-absorbing layer 3 and the gauze 5 are fixed by adhesive bonding. For example, when the gauze 5 is rolled into a ring structure, the bottom of the ring structure is coated with glue and then glued to the top of the water-absorbing layer 3. The structure is simple and easy to use, so that the gauze 5 rolled into a ring structure can be fixed on the water-absorbing layer 3.

[0040] See also Figure 1 As shown, in a preferred embodiment of the present invention, the size of the water absorbing layer 3 is completely consistent with that of the anti-infection layer 2.

[0041] In specific implementation, Figure 1 As shown, the water-absorbing layer 3 and the anti-infection layer 2 are both rectangular structures with exactly the same size, which can save manufacturing materials and reduce manufacturing costs.

[0042] In another embodiment, the hemostatic layer 1 is rectangular, the length of the hemostatic layer 1 is 4-8 cm, and the width of the hemostatic layer 1 is 2-4 cm. More specifically, the length of the hemostatic layer 1 is preferably 5 cm, and the width is preferably 2 cm. Since the hemostatic layer 1 and the anti-infection layer 2 are exactly the same in size, the above conditions also apply to the anti-infection layer 2.

[0043] See also Figure 1 As shown, in a preferred embodiment of the present invention, both ends of the anti-infection layer 2 are provided with adhesive sheets 4 for adhesion.

[0044] In specific implementation, Figure 1 As shown, the adhesive layer is provided on the adhesive sheet 4, and the adhesive layer is used to be attached to the patient's skin, so that the device is firmly fixed and pressed more conveniently. More specifically, the adhesive layer of the adhesive sheet 4 is equivalent to a double-sided adhesive, one side of which is attached to the adhesive sheet 4, and the other side is attached to the patient's skin.

[0045] In a preferred embodiment of the present invention, the anti-infection layer 2 is a chlorhexidine gluconate layer.

[0046] In specific implementation, chlorhexidine gluconate is a commonly used broad-spectrum bactericide and disinfectant. The mechanism of action of chlorhexidine gluconate is to change its permeability by adsorbing on the cell membrane of bacteria, causing the loss of cell contents, thereby exerting an antibacterial or bactericidal effect. It is active against a variety of pathogens, including but not limited to staphylococci, streptococci, Candida albicans, Escherichia coli and some anaerobic bacteria. This drug can inhibit bacterial growth at low concentrations and directly kill bacteria at high concentrations. By setting the anti-infection layer 2 to chlorhexidine gluconate, the safety of this device is improved.

[0047] In a preferred embodiment of the present invention, the hemostatic layer 1 is a hemostatic sponge.

[0048] In specific implementation, the hemostatic sponge can quickly absorb blood and tissue exudate, physically fill blood vessels or wounds, promote platelet aggregation and coagulation reaction, and achieve effective hemostasis. In particular, the absorbable hemostatic sponge can adapt to the size of the surgical cavity. After placement, it will quickly absorb water and swell, filling every gap in the wound surface to achieve the purpose of hemostasis. Common absorbable hemostatic sponges are acetals made from polymer materials such as polyvinyl alcohol (PVA) and aldehydes through chemical reactions (such as acetalization reactions). This material is small in size in a dry state and is easy to operate. After being implanted in the body, it can gradually absorb water and swell and eventually be absorbed. It is non-irritating to tissues and reduces scar formation.

[0049] See also Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the cross-section of the hemostatic layer 1 is rectangular, circular or elliptical.

[0050] In specific implementation, the shape of the hemostatic layer 1 can be selected and set according to actual needs, such as one of a rectangle, a circle and an ellipse, and the corresponding anti-infection layer 2 is also adapted, that is, the shape of the anti-infection layer 2 is consistent with the shape of the hemostatic layer 1. More specifically, the hemostatic layer 1 is preferably a rectangle, and the anti-infection layer 2 is preferably a rectangle, and the sizes are completely consistent.

[0051] To sum up, the utility model provides a hemostatic dressing, which first plays a hemostatic and anti-infection role through the hemostatic layer and the anti-infection layer, and then presses the spiral gauze on the anti-infection layer, which can not only effectively stop bleeding from the patient's wound, but also the spiral gauze facilitates concentrated pressing pressure, thereby quickly stopping bleeding, reducing the patient's hand pressing time, and achieving a better hemostatic effect.

[0052] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
